Re: Oh the security....
The Due Diligence issues can be summarised in one word
All the while an administrator (financial, that is, not systems) can say "Pay us more than you agreed to contractually or we won't return access to your data to you", just what cost/reliability improvements are really there vs rolling your own, if you properly risk-manage this ELE possibility ??
He cannot be serious. Oh, he is....
Dave Coplin, chief envisioning officer at Microsoft [.....] agreed the "main challenge is the human element" as big data forces a change to scientific approach - moving from trying to work out why something happens to a "world of correlation based on sample sizes".
Errr, WTF ?? Yes, statistical correlation based on sample size is useful to validate theories (cf Higgs Boson, etc) - but that's based on a prediction of what should be observed if a theory about "why" is correct.
You don't, and can't, work the other way round. You may get a clue from correlation as to the "why", but that's just a pointer for further research and then working out a further set of predictions that you then validate experimentally.
For the result of applying correlation directly to causation, just look at all the crappy public health policies we've had over the last couple of decades, some of which are at last unravelling.
No wonder HP found Autonomy wasn't worth as much as they thought.
nah, I learnt Algol 68 on an ICL1902 (I think it was) at Kingston Poly in the summer of '72, between Lower VI and Middle VI.
Mind you, our Head of Maths had been offered a redundant IBM M/F but we didn't have the space. Or big enough incoming mains. That would have been fun.
I've used Microsoft Exchange a few times over the years, but it is a pain to configure and still needs a lot of work.
The latest complaint from my users is that as soon as they change a new appointment to "all-day", it automagically changes the status from "busy" to "free". Which leads to appointments being put into peoples' holidays, unless they notice this and change it back again. Needless to say, googling reveals lots of moans about this and the inevitable "fix" that "fixes" an entirely different issue, nevertheless being flagged as the "answer" by some Microsoft forum moderator.
"The first person to create a Linux-on-ARM compatible drop-in Exchange replacement will become a very rich person indeed. But to the best of my knowledge it hasnt happened yet."
I see arm in the available architecture list....
Not, of course, that a few people will become rich on the back of this. But plenty will make a decent living, which is acceptable to me.
Re: A timely reminder to all
The most recent timely reminder (before this one) was that O2 wholesale outage in Northamptonshire (and surrounding areas) when it turned out that Level 3 had a PoP in a light industrial unit, when an adjacent unit caught fire. So much for VESDA and automated fire extinguishing systems...
Re: The real biggest holdup
How I wish I could upvote that 100 times. Closed hardware is the biggest barrier to Android updates and alternative "ROM"s - look at devices like the Galaxy Y S5360 with the Broadcom BCM21553 chipset - which doesn't have an updated BLOB so no chance of Cyangenmod running on it - even if it did have enough memory.
Give them credit. It's quite an achievement to find a courier worse than ShittyLink, wot they always used to use.
Re: 'thought leadership'?
Yeah, Dr. Peter Cochrane OBE suffered the same fate. If he'd been listened to, we'd have FTTP and picocells nationally by now.
But, as ever, the visionaries were ignored.
Re: Good Riddens
You're talking about data over powerline devices within a property. This article is about data over telephone wires into the house - the delivery of internet services into a property.
Some similarities, but also some huge differences in the issues. For instance, modern "outside plant" is built with twisted pair wiring that has a reasonable degree of transmission-line characteristic at (low) radio frequencies. Mains cabling within a property has no such characteristic.
Re: Not a problem for DSL
Tell that to everyone who's broadband goes TU once the house next door gets covered with christmas lights and their dodgy controllers..... I guess I should have been a bit more generic about what I meant by "high-powered transmitter".
It works both ways, too - not only does the RF electrical signal leak out as electromagnetic waves thanks to the (very) imperfect transmission-line qualities of the local loop, but for the same reason the data signal is susceptible to high field-strength radio signals. There is clever defence against impulse noise (the most common universal source) but a high-power transmitter in your vicinity could well play havoc with the xDSL signals.
Re: Learning from mistakes
"That's the design of DNS - single master - not much Microsoft can do about that...."
Errr, no. How the database is setup is entirely separate from the client view of the domain. Single-master is the original design of the most-commonly used DNS server - ISC BIND - which is where you may have got that idea.
To give them a little credit, the MS DNS server gets its data from AD, so the data is mirrored at each AD/DNS server. However, its tight integration with AD makes the validity of the AD structure a single point of failure, and reduces the speed at which rollback can take place. As shown by this outage, it would seem. It's also a bit of a security risk to run DNS and AD on the same server, but I presume MS have separate caching servers facing the outside world to manage that risk (Ahem....).
Powerdns can use a range of backend databases, and using, for instance, PostgreSQL, can have a multi-master backend, with sub-minute rollback if set-up right.
Re: "You really are becoming the replacement Eadon"
"All the IP stack stuff is in the registry"
Whaaaat ??? Since when did executable code live in the registry ??
Oh, I see, you meant to say "All the IP stack configuration stuff is in the registry"
Which broken configuration method that Windows offers you choose to employ when porting (and it was impressive for MS to come up with an even more broken system than .ini files) is pretty irrelevant to the heredity of the code you're porting.
Yabut - they claimed it was available across all of Manchester, when in fact it was only 50%.
Now, if it was 95%, I might have let that pass. But not 50%. No way. That's a blatant lie. False advertising. End of.

"ROI and TCO projections are always the problem"
Err, so apart from the fact that the financials don't work, this is an excellent solution.
Remind me again why VDI is meant to be such a great idea ?? Surely it isn't just being punted at the hapless users by the vendors looking to make increased profits ?? Never !!!!!
Re: I would imagine...
Whaaaaattt ?? £600 a year per user ?? That's 2 desktops a year.
Make it £5/mth, or maybe £10, and I might bite.
And upload speeds are.....
Yep, upload speed on this "top-of-the range" product remains at a staggeringly slow 12Mb. And my 60Mb service is still stuck at 3Mb upload. Years after we were promised an upgrade
Didn't mention that, did he ?

Re: Not just broadband...
You had signed a contract, but BT breached it, rendering it void.
Re: Terrible Idea. But...
If what you're saying is true, then there must have been dramatic changes in BT Business Broadband support in the last 4 years. Which I don't believe.
I thought I'd got a result when someone promised me that he'd take personal responsibility for resolving an ongoing issue my client had. He gave me his name. I asked him what number I could contact him on, and he told me I could get him on the standard 0845 number.
So when the problem wasn't resolved, I called that number and asked for him. I was told he worked in another office (there were, apparently, three offices that calls to the number were distributed to). Could you transfer me, then, please ?? No, they couldn't. That was the final straw. To use the "I'll take personal responsibility for the issue" line as a tactic to get the caller off the line is despicable beyond belief. And for BT to be unable to transfer calls between offices when that's a service they sell...... (Yes, I know they can but just wouldn't)
On the basis of that as the lowest point of (many) low points I will never, ever, ever use BT as an end-user customer if there is an alternative. Ever again. Never. Is that clear ??
Bailiffs at big companies
The episode of Bailiffs where they pitched up to enforce a debt against Fujitsu was a great laugh. They were very patient in explaining to the security man on the gate that he didn't have the right to prevent them entering and listing goods for seizure. The security guard was clearly very poorly trained as he didn't believe them <cough>. They were on the point of driving the van through the lowered barrier when senior management finally made the correct decision.....
You really should have known
If you believed BT's "go-live" dates for Infinity anywhere in London, and work in the telecomms business - well, what can I say. I don't have the "insider" knowledge that you ought to, and wouldn't believe them. Just look at how often the date for the exchange local to my organisation - Southwark - has been pushed back.
It's most obviously the case in London that BT are shit-scared of their leased line revenue vanishing on the back of business infinity - though that was irrelevant to me as our copper (or possible ali, going by the attenuation....) is EO.
I'm just so glad that Hyperoptic are now doing business leased lines. 100Mps for less than the price of 4-pair EFM. Perfect timing for me, too.
Re: Stupid certification programs
Most of these certifications are dumb multiple choice questionnaires that can be passed with rote learning.
I've sussed multiple-choice tests. Do them by eliminating the "obviously wrong" answers. 90-95% of the time you're then left with the correct answer(s).
As I continue to bore everyone with, the only exam I took where my understanding rather than my memory was tested was an open-book exam in my 3rd year, on electronic circuit design. Set by (then) Dr (now) Prof Robert Spence. And therein lies the problem. You need top-notch examiners to set papers of that quality.
Underscores the problem with vendor certifications
It's quite simple.
Professionals have their capabilities certified by the appropriate professional bodies.
Do you see Doctors gaining "Merck approved diagnoser" certification ?? Or Civil Engineers with "Accor approved steel designer" ?? Or Physiotherapists with "Mueller certified taping practitioner".
Of course not. Because it's just plain Wrong.
It is the same for IT Professionals. You need a degree and continuous professional development. Anyone waving a vendor certification around has, by very definition, too narrow a view of the landscape to be called a professional.

Pah. I'll raise you 50p to see Genesis when they were supporting Lindisfarne on tour and the venue (Kingston Poly) was too small for Lindisfarne to be arsed to play at.

An Rh/CentOS convert, me
Whereas I started with Slackware, found rpm a better packaging medium (Around RedHat 2, IIRC) and (obviously) gravitated to CentOS once RHN went payware.
Also, RH was more System-Vy whereas Slackware was more BSD/SunOSy around the init stuff, which I felt more at home with having learnt SVR2 in depth in '84.
ARM systems ('specially the slug) got me familiar with Debian, certainly came to understand and like the philosophy, Now that CentOS 6 is a full re-install rather than an upgrade (despite remaining at 2.x kernel, whereas squeeze to wheezy is 2.x to 3.x kernel, but only needs an upgrade), the inertia keeping me on CentOS on the '86 architecture is gone. Despite being a long time RH/.rpm guy, I'm sold on Debian/.deb now. Overall, it definitely does it better - maybe even "right". Wheezy multiarch is neat, too.
Re: What has it got in its pocketsess?(@ Chris Miller)
The telco certainly has the serial number of your SIM, and the IMEI(s) it's been inserted in, but given the ease of a MAC address being modified (compared to those other two) I can't see the utility of hanging on to it. And when you put the SIM into another phone, the MAC address will change. And, as I noted earlier, the association with the device is by IMEI.
OTOH, public WI-FI providers apparently do - Virgin Media on the tube, f'rinstance. But you voluntarily trigger that association when you sign-in to an AP.
Someone else has already made the comment about "cloudy" providers - that you may find yourself held to ransom by administrators (not the system type :-) ) or other bean counters in the event of bankruptcy or administration. Unlikely, I'd admit, in Google's case, but not impossible.
If you Go Google, there's the not-insignificant risk that they'll drop an app you've become reliant on. This absolutely MUST be factored into the analysis.
I challenge you, as a small business, to get sufficient information from a cloudy provider to enable you to carry out due diligence on their system security and resilience. If you're content to believe SalesSpeak, so be it.
Finally - your comments about Google Mail. Sure, the Spam disappears. In my experience, though, so does far too much of the email you need. Their false positive hit is far, far, far too high for a professional email system - and where's the sense in having to plough through the Spam folder looking for the emails you missed - might as well have put the Spam in the inbox in the first place. I speak as one who, with good exim+sa-exm and amavis, manages <1% false negatives and 0 (yes, 0) false positives. Which is absolutely crucial for my people. And I get the bizarre pleasure of teergrubing the spammers :-)

Competent beyond belief.
Re: Not so good for real time...
But shurely using audio broadcast entertainment channels for time-setting is a technology that's had its day, wot with ntp being pretty much universal ?? And if you're off-net, there's always MSF.
Because, as you rightly say, Virgin is coax, whereas BT is twisted pair. Which makes one hell of a diiference on how much bandwidth it can support.
I can't think of a way to turn the difference between the two technologies into MarketingSpeak.
Re: Sad to see them go
Yabut - EFM is at a minimum 4 times the price of BE bonded. My need for 10Mbps uplink isn't valued at that, yet.
As I mentioned, EFM prices are said to be dropping - they do seem to be, but not quite to the level that I'll jump, yet. And you need to sign for 3 years or pay >1K upfront - also not good.
Sad to see them go
Agree on the Bulgarians - the most helpful call centre you could hope to find.
As I've bitched about far too often already, at the work location - no FTTC, exchange-only lines, no Virgin Media, too small for the ex-BE Hyperoptic peeps - a reasonably-priced bonded service from BE was an excellent solution.
I'm quite sure this service will be discontinued by Sky - it's not as if they're into niche services. The only saving grace is that EFM prices are dropping, and rumoured to be descending further (so don't sign up to 3-year EFM contracts, people !!)
I have to say - Katherine Parkinson is absolute genius in "Before the Party" at The Almeida, finishing its run tomorrow night.
Re: Pear shaped matter?
You, sir, owe me a new keyboard.
That was another migration, done (and proudly announced by M$) some years ago. Some results from the Choccy Factory say this was in 2000. I remember it as later, but then at my age time does travel faster.
Needless to say, it involved all sorts of glitches and downtime. And about 4 times as much compute power to deliver the same service.

Re: Die Hard II
All they needed to do was give out an incorrect atmospheric pressure for the location.
Rememberer a documentary on a company that flew cargo (mostly) for the oil exploration - Lion Air. Pilot coming into land at a Nigerian field - pointed ouit the wreckage at the side of the runway where the tower had given out incorrect pressure, pilot thought he as a few metres above the runway when he, errr, wasn't. Bang,
Re: Why me?
It's because you're too close to the exchange. It's a well-hidden fact, but if your line is connected directly into the exchange without going via a street cabinet (known as an "exchange-only", or EO line) then VDSL (the modulation technique used over the short bit of copper from the fibre termination to your property) is not possible.
It's theoretically possible to put the kit that would be in the big cabinet linked to the street cabinet directly into the exchange, but here are potential interference issues that mean this isn't approved.
Last time I looked, there was some waffling from BT about what they proposed to do about such subscribers (it's a surprisingly large number) but nothing concrete.
Re: The technology is rather relevant there
"Once you are at a central office, bandwidth is essentially free"
I suggest you look at BT wholesale bandwidth charges to ISPs if you believe that.
Re: You are right.. and wrong
I've been in love with Supermicro for ages :-) They seem to get server design Right, especially mid-range, unlike Dell (wot, only 2.5" drives in your 2U server ?? I'm not made of money)
Big plush offices
A sine qua non for an SME (especially in the tech world) going bust is having recently moved into large, plush, expensive offices.
So whilst some of this article is questionable, I'm with Dominic on this one.
Amidst all this panic, let us not forget that Scallywag was taken off the market and bankrupted by John Major's lawsuit, not (as it turned out) for telling a falsehood, but solely getting the identity of the person he was shagging wrong, for playing away he was. This under the law as it existed then. How much worse it will be now.
Of course, if they'd said at the time that it was the fragrant Edwina Currie, not a soul would have believed them....
Disgraceful waste of our money
Had a go at our County Councillor (Kent) when he was trumpeting this BDUK money.
I pointed out that BT always say that things just aren't commercially viable, drag their heels, and then all of a sudden when either:
i) the profitability is staring them in the face
ii) competition arrives
it all starts happening.
I objected to my money being spent to (effectively) contribute to BT's profits.
He didn't see what I was on about, kept trumpeting how people who wouldn't get BB otherwise would get it. I said that, in reality, they would get it too, maybe a little later, but arrive it would.
This from a Government that claims to support the free market. Not, methinks.
Jobs' legacy ?
What a wonderful legacy Steve Jobs left, having made clear his desire to destroy Android. His strategy (for it is his) may end up destroying Apple rather than Android.
